LAST.

Specification of Letters Patent.

Patented Qct. ii, 191%.

Application filed March 28,1917. Serial No. 1573M.

Z 0 all whom it may concern:

- Scioto and State of Uhio, have invented oer tain new and useful Improvements in Lasts, of which the following is a specification.

One of the objects ofthe invention is to produce a simple, strong and practical last which can be broken. or flexed so as to facilitate the ready removal of the last from the shoe and so that the shoe during the removal of the last will not be marred, broken, or pulled out of shape.

it has been found practical to construct a last so that it will comprise toe and heel parts which have provided between them a pair of main bearing pins which extend transversely of the last. The toe and heel parts preferably bear directly against these pins which are held inplace so that the heel part can swing relatively to the toe part in order to break or shorten the last. It has also been found practical to secure said toe and heel parts together by a link that is directly connected at one end to the toe part and at the other end to the heel part by small pivot pins or rivets that pass through the end portions of the link. It is also preferable, the construction of such lasts, to provide a tension spring which tends to maintain the parts of the last in unbroken position. This spring is preferably located below the center of the main bearing pins and it is also located below the link just referred to.

According tothe present invention this link is composed of pivotally connected. members, preferably a pair of members which are connected by a pivot that is located adjacent to the main bearing pins.

Witn this construction a last can be made Fig. 2 is a plan view of the last shown in Fig. 1.

Fig. 8 is a vertical sectional view taken as on the plane indicated by the line 33 of Fig. 2.

Fig. l is a sectional view showing the position of the parts of the last when in a full broken or extreme shortened position.

Fig. 5 is a sectional view taken as on the plane indicated by the line 5-5 of Fig. 1 looking in the direction of the arrows.

Fig. 6 is a vertical sectional view taken. as on the planes indicated by the broken lines 3-6 of Fig. 1 looking in the direction of the arrows.

Fig. 7 is a view of the toe part of the last and of the end thereof nearest to the heel part of the last.

The last is designated by the reference character A and comprises the forward or toe part B and the rear or heel part C. In the formation of the last these two parts are made integral with each other from the same piece of wood and they are subsequently separated, as by sawing, along the lines X Y, X Z, M N and Y 0. After the proper sawcuts have been made the parts of the last can be separated by splitting the wood along the line Z M. This construction is employed where it is desired to have horizontally ex tending overlapping shoulders between. the toe part and the heel part 011: the last. lt is practicable, however, to make the last without the employment of the overlapping shoulder. Preferably some time before the heel. and toe parts are finally separated a hole is bored at Y to form grooves for the reception of the main bearing pins D and .D.

The material which formerlyoccupied the space defined by the lines X Y and Y O is removed from the finished last and there is left a Vshaped opening which permits the parts of the last to assume the position shown in Fig. 4-, as will be manifest from an inspection of the drawings. By suitable apparatus a cavity or opening, such is shown in Figs. 3 and 7 can be made in the toe part of the last and a similar cavity 1' opening can be provided in the heel part of the last. Into the upper part of these cavities or openings there extends a link E one-end or which link is secured in place to the toe part of the last by a small rivet or pin '6 and the other end of this link is secared to the heel part of thelast by a small rivet or pin 5". There extends into the lower portion of each of these cavities or openings a tension spring F, one end of which spring is secured by a small pin or rivet f to the toe part of the last and the other end of which spring is secured by a small pin or rivet f to the heel part of the last- This spring may be omitted in some forms of last but it is preferable to include this spring in the last and it is arranged so that it tends to maintain the heel and toe parts of the last in extended position.

An important feature of the present invention resides in the constructing of the link E-wliich is of metal-above referred to of pivotally connected members and in the form shown. this link is made of a pair of members G and ll: which are pivotally connected by means of a rivet or pin K. The member G may be considered to comprise a pair of leaves 9 and 9" which are connected by the metal at g In other words, the member G is of U-shape, but a single plate or a pair of connected plates could be em ployed at this place. The pivotal connection between the members .G and H is located at or near the center of the link, to

wit, in the central portion of the link; in other words, intermediate the place where the ends of the link are connected respec' tively to the heel part and toe part of the last. The ends of the link members which are connected by the pivot pin K may be considered as the fixed ends of said members and the ends of said link members which are connected to the toe part and heel part re spcctively may be referred to as the movable or free ends of the link members. I? hen the parts of the last are in the extended position shown in Fig. 1 it will be observed that the longitudinally extending line 6 a, e 0 pass ing through the centers of the pivot pins 6 and e is located below a horizontally and transversely cxtendinqline which asses it i through the centers of the main bearing pins D and D, and it will also be observed that when the parts of the last are in extended or unbroken position the center Kc of the pivot connection K is on this line c 0e c, if the members of the link arcfree to assume this position. AS the parts of the last start to move from an extended. or unbroken position toward a broken position, as by an. upward swinging movement of the heel part of the last, the center of the pivot connection ll starts to move toward the line passing through the center of the main bearing pins D, D-. -Theupward movement of the pivotal connection is a limited movement andsai movement is or can be arrested by the link member G striking" the roof L of the cut-Ont portion in the toe part of the last andan upward movement of the heel part can continue to take place due to the flexing or breaking of the link E, breaking is permitted as a result of the pivotal connection at During this last mentioned period the member H of the link E will swingnbout the pivotal center Kc.

which flexing or 56 It is practical to make this construction so that the pivotal center. c will proximate or substantially coincide with the center line passing; through the main bearing pins D, D when the upward movement or" the member G is arrested, as by engag ment with the roof l1, and it is also practdzal to make the construction so that the center lie will move, from a position below the line passing through the centers of the nniin bearing pins l), D to a position above this line before the 89 movement of the member G is arrested, as by engagement with therool L. it will be noted that the pins c and c are on opposite sides of the vertically or transversely extending" plane which passes through the 35 centers or" the main bearing pins D and if). When theparts of the last are in extended or unbroken position the center of the pivotal connection between the members G and H which constitute the link is preferably lo 90 v 1 During the latter portion of the movement of the heel part toward the toe part this rivet K remains in a substantially fixed position relative to the main bearing pins D and D. The pivotal connection or the link members always remains proximate the center line of of said pins. The link construction is such that the link always holds or maintains the last parts in proper position relative to each other whereby the last parts will remain assembled whethr they be in an extended or unloroken position or a full broken position, or a position intermediate the unbroken and broken positions. The link construction is also such that the swinging of each link member relative to the last part to which it is connected is a limited movement that takes place during the first portion of the movement for breaking" the last and during; the final movement of the 1 last parts toward iinbrokcu position.

' The main bearing pins it) and D have shoulders or collarsthereupon (preferably sharp) designated by a? and d which can be forced into the wood so as to servevas means for retaining the bearing: pins D and v D in position, as against 'any'longitndi nal displacement; 'withont necessitating the employment of a screw or nail for S6011?- ing said bearing pins D and D to one or the other of the parts of the last. The linkE is, of course, located between the bearing pins D and D and can thus serve to maintain the parts in proper position when the last is in use. I -The improvements herein set forth are not limited to the precise Construction and arrangement shown and described for they may be embodied in various forms and modifications Without departing from the spirit and scope of the invention.
